deps(snyk): update snyk snapshot

[snyk-bot]

Why this PR?

a weekly update of the vulnerabilities snapshot for lighthouse

[patrickhulce]

hey @aviadatsnyk think could we get snapshots more similar to the one in #5080?

that makes it clear to see what's being added/removed and much smaller payload to keep in our bundle. since you're running your own script now it's somewhat out of our hands 😄

[aviadatsnyk]

Of course!

[paulirish]

@aviadatsnyk thanks!

fyi #5080 has now been merged. given that, we think it makes sense to keep the https://github.com/GoogleChrome/lighthouse/blob/master/lighthouse-core/scripts/update-vuln-snapshot.sh file in place (it was deleted in #5162)

that way your bot should be able to run this script, commit and PR like it has been. and we'll end up with the smaller cleaner files. sg?

I'll close the other PRs since this has all the context. (And I figure the bot will open a new one rather than update 5306 ;)

cheers.

[aviadatsnyk]

totally agree. btw - the script was not deleted in #5162 (the PR wasn't merged) - so I think we're good.
I'll make future PRs submit the cleaned-up snapshot.
